Hi,
Where did you find the missing dll for PostgreSQL ?
DependencyWalker indicates qsqlpsql.dll needs libpq.dll in order to work.
So I downloaded PostgreSQL binaries from the official site, and got
libpq.dll.
But it doesn't work with PyQt5.7.1/Python3.5.2/Windows7-64bit, because
libpq.dll was compiled against Visual Studio 2013, and Python3.5.2 needs
Visual Studio 2015.
Did you have to compile PostgreSQL yourself ? (it's not an easy task at all)
Thanks.
